After reclassifying from 68W, which MOS will yield a better career advancement, 68C or 68V?

68W will actually lead to a better career advancement with more openings at the Senior enlisted level than either of the other two. Plus additional training opportunities like flight paramedic and the new program which I can never remember the name of. It's the Army version of what the Navy calls an Independent Duty Corpsman. It's a six month course to put you somewhere between a medic and a PA

My impression is that civilian work as an RT is better than LPN, however, you’ll likely have an easier time finding programs for advancing your credentials, such as LPN to RN/BSN. I will caution you that many desire to transition from LPN to RN, but active duty has many challenges to completing clinicals. I hope that helps shape your decision.

As far as a stepping stone for advancement up the enlisted chain or educational opportunities and advancement within the military or civilian medical, no question it would be 68C. But then again I’m biased being a former SSG 68C.

Get out go to nursing school then go back

I am a current 68C and have been nursing for 5 years, and a senior in college for my BSN. I also work in a clinical setting so I may come across biased but I believe 68C has more opportunities. Not only can you find yourself working on other floors and learning new practices it’s also easier to move your LPN to a ADN or BSN. As far as the concern for clinical completion for your degree I have never had a issue with completing my clinicals as long as I communicated my required days with my floor. Medical side of the Army is not the same as forcecom, they want to see you advance your talents and education. My 1SGT during boards doesn’t like seeing a SPC who doesn’t have at least a associates degree. In my experience it’s not that way on the force side of the house. Hope this helps.

My answer will be biased since I'm an RN. I reclassed to 91C (Practical Nursing) after I ESTd and went to the reserves. I feel that you'll have more opportunities in nursing.

As a 68C, if you’re planning on staying in the army and want to move up the ranks, stay 68W. There are infinitely more opportunities for schooling and identifiers.
With that being said, if you’re looking to get your training and leave the army for civilian sector, 68C is a great stepping stone as well as it leaves a ton of options open for specializations on the outside.
